The level of hepcidin mRNA expression in RCC was not related to the tumor grade (mean ± S.D. grade 1, 8.34 ± 8.66; grade 2, 16.36 ± 18.96; grade 3, 19.79 ± 23.12, P = 0.4249, Figure 3B) or the tumor stage (pT1–2, 14.88 ± 19.15; pT3–4, 18.56 ± 20.13, P = 0.4348, Figure 3C). The gene discussed is HAMP; the disease is renal cell carcinoma.
